SA Offer at DB and Haven't Heard from Other Places, What Now?

Deutsche Bank extended me an IB offer yesterday, shortly after the final round interviews. They're giving my two weeks to decide on the offer. I applied relatively late to other places, so I've only done a few HireVues so far and have one additional first round coming up. I don't want to just take the first offer I get but also really don't want to drop this offer in case nothing else works out (despite DB being in a bad spot right now), and I literally haven't heard anything from the other 10 places I applied.

What do you guys think I should do? Should I accept and withdraw all my other applications? Should I decline and hope a better offer comes? Any ideas on DB's outlook and the likelihood of a return offer?

Thanks in advance.
